I wonder why the big hoopla la between Chinook and Killer Whales? Sure, it is what it is, a food source. If all the Chinook were gone you think they would stop searching for food? They're not so stupid that they would starve because no kings to eat. They move to the next best thing. Seals, Coho, Pinks etc. A few years ago KW were in Dyes Inlet feasting on a big return of Chum. Also some rouge KW went into Hood Canal and wreaked havoc on an excessive population of Seals there. They are opportunists like most other predators in nature. I think they deserve a little more credit than they get.
